Problems solved by technology

However, in the prior art, when adjusting the content of the layout, the coordinate system of the layout generally adopts the default screen coordinate system of the mobile terminal, so when the mobile terminal is in different postures, the positions of the cameras are also different, which will lead to The location of the starting point is also different
Therefore, when mobile terminals with different postures are used for human eye tracking, if the same layout parameters are used, the viewpoint images to be displayed by the pixels in the display screen may be confused, so that the naked-eye 3D display effect cannot be achieved.
If you want to use mobile terminals with different postures to track the position of human eyes, you need to calibrate the layout parameters corresponding to the mobile terminals with different postures, but this will increase the calibration work of the R&D personnel, which is time-consuming and laborious

Abstract

The embodiment of the invention discloses a human-eye tracking-based naked-eye 3D display method, device, terminal and medium. The method comprises the following steps: determining a current layout coordinate system corresponding to the current posture of the mobile terminal, and obtaining a camera position and layout parameters calibrated in advance; wherein, the current layout coordinate systemkeeps the position relative to the screen of the mobile terminal unchanged during the rotation of the mobile terminal; acquiring imaging coordinates of left and right eyes of a viewer in an image captured by a camera of the mobile terminal; according to the imaging coordinates and preset layout parameters, adjusting the display content of the mobile terminal with the camera position as the layoutstarting point in the current layout coordinate system. By adopting the technical scheme, the mobile terminals with different postures can share the same layout parameters when performing naked-eye 3Ddisplay.

Description

technical field [0001] Embodiments of the present invention relate to the field of naked-eye 3D technology, and in particular, to a naked-eye 3D display method, device, terminal and medium based on human eye tracking. Background technique [0002] Glasses-free 3D display technology refers to a 3D display technology in which viewers can directly watch three-dimensional images with naked eyes without wearing special 3D glasses, presenting a 3D effect. In the process of realizing naked-eye 3D display, if there is no human eye tracking, the fixed light distribution requires the user to find a suitable viewing position in front, back, left, and right to see the ideal three-dimensional effect. When the viewing position is inappropriate, the light that should have entered the left eye may enter the right eye. At this time, the right eye can see both the left image and the right image, which is prone to crosstalk and poor user experience. Therefore, it is necessary to track the pos...
